I get a black screen in up to date FF and Chromium when Sneek Peeking cube-gold.blend and also when exporting to gltf and open the gltf via App Manager.

Ubuntu 20.04.4 LTS, 5.18.2-051802-generic

Verge3D 3.9.1

No, same with the silver one.
You find the exported gltf of the gold-cube attached.
I also found this error message in the browser console:
```

do the stock demos open on your system?
does it work with v.4.0?

All the demo gltf’s that come with 3.9.1 work fine on my system.

Once a file is generated via Blender 3.2 with the Verge3D 3.9.1 Add-on, the gltf is buggy.

I just downloaded verge3d-blender-4.0.0-pre5 for testing and it works fine in all cases. Sneek Peek and exported gltf, everything works as expected.

I had to copy the applications folder from 3.9.1 because there is no applications-folder in verge3d-blender-4.0.0-pre5.tar.xz

(I just realize there is right now a stable 4.0 availabe! I will try this one asap but I guess it will work. )
